摘　　要：由环氧树脂、甲基四氢苯酐和KH550处理的空心玻璃微珠制得浮力材料,采用全海深环境模拟装置,参考美国军用标准MIL-S-24154A,研究了110 MPa全方位静水压下浮力材料的密度对其吸水性的影响,并对静水压测试前后浮力材料的力学性能作了测试。结果表明,随着浮力材料密度的降低,其吸水率升高。测试前后材料的压缩强度和弹性模量未发生明显变化。同一静水压下,表面喷涂聚脲弹性体的浮力材料吸水率更低。极限破坏压力试验表明,142 MPa的静水压下浮力材料完整无破损,能够满足全海深环境的应用要求。The syntactic foams were prepared by epoxy resin,methyl tetrahydrophthalic anhydride and KH550 treated hollow glass microspheres. The effect of syntactic foam density on the water absorption of the foams under comprehensive hydrostatic pressure 110 MPa was investigated using the all deep sea environment simulation device and reference to the US military standard MIL-S- 24154A. The mechanical properties of syntactic foams were tested before and after hydrostatic testing. The results showed that with the decreasing of syntactic foam density,the water absorption rate was increased. Before and after the test, the compression strength and elastic modulus of the material did not change significantly. Under the same hydrostatic pressure, the water absorption rate of the syntactic foam with polyurea elastomer surface coating was less than that of foams without coatings. The extreme fracture pressure test showed that the syntactic foams was intact without damage under 142 MPa hydrostatic pressure and met the application requirements of the all deep sea environment.
